Westbound lanes of Main Street will close to traffic the night of Friday, May 10, as the City’s contractor on the Floyd Branch Watershed drainage project installs box culverts under the roadway. Closures will also occur nightly beginning Monday, May 13, through most of next week.

The closures are expected to take place from 8 p.m. until 6 a.m. the following morning, and eastbound traffic will not be affected. Crews will not be working on the project Saturday or Sunday nights.

Signs will be placed in the area alerting drivers of the lane closures. Westbound traffic on Main Street will be detoured south on Interurban Street to Kaufman Street. From Kaufman, drivers will be directed to the northbound US-75 frontage road. Traffic will be able to turn left on Belt Line Road or continue north on the frontage road. (See map.)

The project will improve drainage in the Floyd Branch Watershed, which collects drainage from 2.6 square miles in south central Richardson and eventually flows to White Rock Lake. The project will add capacity to the area’s drainage system by adding new underground drainage pipes north and south of Main Street between US-75 and the DART rail line. No existing open channels will be enclosed.

Improvement work also includes the installation of a new right turn lane along westbound Main Street from Interurban Street to the US-75 northbound frontage road and construction of a new bridge over Floyd Creek Branch at West Phillips Street. In addition to improving the decades-old drainage system, improving drainage system deficiencies will also allow for the possibility of future development since current conditions have been a costly deterrent to redevelopment along the City’s Main Street and Central Expressway corridors.
